Landessprache vs Muttersprache
native language
'Muttersprache' and 'Landessprache' can sometimes be the same language, but they do not mean the same thing. A 'Muttersprache' is the language a person first learned as a child. So it belongs to a person's personal history. A 'Landessprache' is the language that is spoken officially or primarily in a country or region. Learners often confuse the words because, for example, German can be someone's native language and is also the national language in Germany. But a person can live in a country whose national language is not their native language.
Landessprache
Vor der Reise lernt Tom ein paar Sätze in der Landessprache.

Muttersprache
